C #: Как найти доступный порт в диапазоне определенных портов TCP?

Я нашел способ сделать это:

private static int initialPort = 6001; // initial port to search from

public static void StartServerTCP()
{
    bool serverSet = false;
    while (!serverSet && initialPort <= 7000)
    {
        try
        {
            Console.WriteLine(Dns.GetHostName() + ": (Server:TCP) Trying to setup server at port: {0} [TCP]", initialPort);

            serverSocket.Bind(new IPEndPoint(GetIP(), initialPort));
            serverSocket.Listen(0);
            serverSocket.BeginAccept(AcceptCallback, null);
            Console.ForegroundColor = ConsoleColor.Yellow;
            Console.WriteLine(Dns.GetHostName() + ": (Server:TCP) Server setup completed at port {0} [TCP]\n", initialPort);
            Console.ForegroundColor = ConsoleColor.Gray;
            serverSet = true;
        }
        catch (Exception)
        {
            Console.WriteLine("\n" + Dns.GetHostName() + ": (Server:TCP) Port <{0}> is busy, trying a different one\n", initialPort);
            initialPort++;
        }
    }
}
